I WARREN \V. COLE, OF PORTLAND, MAINE.

METAL SGREEN;

Application filedNovember 30, 1917. Serial No.

To all whom it may concern Be it known that I, WARREN W. Conn, a

citizen ofthe United States, and resident of Portland, county ofCumberland, State of Maine, have invented an Improvement in MetalScreens, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts in each of the several views.

This invention relates to window screens of the: type adapted to beslidably fitted to guides for use at the upper or lower sash of awindow. More particularly the invention has to do with a screen of thistype having a solid metal frame with guide ribs at its sides fittinginto grooves of molding members preferably of wood adapted to be fixedto the window frame at the sides of the window opening. Such aconstruction presents marked advantages as-compared with either a woodframescreen, or with a hollow metal frame screen in respects that willbe better understood from the following detailed description taken inconnection with the accompanying drawings and the distinctive featuresof novelty will therefore be pointed out in the appended claims.

Referring to the drawings Figure 1 is a front elevation showing a screenconstructed in accordance with my invention applied to a window;

Fig. 2 is a partial transverse sectional view showing the manner offitting this screen with respect to the window sash;

Fig. 3 is a partial front elevation showing a portion of the screenremoved from the window;

Fig. 4 is an edge view of the screen portion seen in Fig. 3;

Fig. 5 is a partial plan view of the screen portion seen in Fig. 3; and

Fig. 6 is a plan view of the screen with the molding guides in sectionand with an intermediate portion of the screen broken away.

An ordinary window frame is indicated at .10 with usual upper and lowersliding sashes 11, 12 respectively. The screen of my invention consistsin a solid metal frame 13 7 produced in any suitable manner as byelectric welding the corners, so that the frame is made into a unitarymass of metal all the way around. The wire mesh 14 may be secured to theframe b soldering or in any other suitable way. 1 1 accordance with mySpecification of Letters Patent.

Patented Nov. 8, 1921.

invention the sides of the frame 13 are rabbeted to formcentral'guideribs 15 which project out some little distance from the opposite sidesof the frame. The rabbeted edge'of the frame on-one side is equippedwith bow springs. 16 riveted or otherwise fixed thereto as seen at 17,these springs being located at each-side of the rib 15 which is shown asreduced in thickness along this part thereof as seen at 18 so that saidsprings may be of greater width and still lie wholly within the planesof the sides of the frame. The ribs 15 are adapted to fit into thegrooves of molding strips 19, 20 preferably of wood, and fixed at thesides of the window frame. These molding strips have the grooves thereinso formed that the inside lip 21 of the moldin is of a thickness topermit the screen to be c oselyfitted against the bot,- tom of the upperwindow sash as seen at 22, thereby preventing the entrance of insects.Thegroove 19 in the molding piece 19 is relatively shallow while thegroove 20, in the molding piece 20 is much deeper, this being the sideat whichthe springs 16 are located, thus permitting the screen to beeasily taken out and replaced by moving it to compress the springs 16and remove the 'rib 15 at the left, as shown, from the shallow groove 19A suitable lift 23 may be fixed centrally of the bottom of the screenframe affording a convenient hand hold.

Among the advantages to be noted for the present construction are thatwith the metal screen running in slide ways formed by wood molding itcan be readily made to fit window frames presenting some littleirregularities by merely planing the back of the molding strips, whichto permit this are preferably made initially some little thicker thannecessary. It is to be observed that even if these molding strips are ofrelatively thick stock, since the screen frame itself is relativelynarrow, the window opening is not reduced materially by the screen.Likewise if a screen is too tight in its guides the back and side can beplaned enough so as to make the guide yielding to the requisite degree,or if the screen istoo loose a slightly wider or thicker guide can beemployed. With the use of the grooved molding guides, the groove 20 atthe side where the springs 16 are located may be made relatively deepand the metallic tongue or rib 15 correspondingly wide so that thescreen frame will cooperate properly with the molding guides I tial anddo not bend easily,

and continue easily operative therein even though the molding guides maydevelop more or less irregularity from shrinkage or other distortion ofthe window frame, it being of course possible to make the ribs 15 widerin metal, than they could be made in wood without rendering them liableto split oil? or become damaged. The springs 16 being exposed on theface of the screen frame can be readil finished, and are accessible forattention, asfor wiping off when necessary, whereas with the springshoused in the grooves'of the frame as usual in previous constructionsthey are difficult to reach for any attention that may be necessary.Further advantages of the use of the wood moldingguide pieces are thatthey are substanso that the metal screen frame will always slide readilytherein, and having no sharp corners they are not apt to tear lacecurtains or the like which might blow out of the window, or lacerate thehands of one having occasion to reach through the window as for washingthe same. The screen frame itself being of solid metal avoids a tendencyto accumulate moisture within itself such as to cause oxidation or rustas would be the case with a' hollow metal frame orwith a wood frame. Thesolid metal construction alsopresents the same strength with a greatdeal less stock as to bulk of the frame than would a hollow frame andhardly atall obstructs the field of vision through the window. I amaware that the invention may be embodied in other specific forms withoutdeparting from the spirit or essential attributes thereof,'and 'Itherefore desire the'present embodiment to be considered in all respectsas illustrative V to be secured to the sides of the window frame andhaving grooves therein to receive said ribs. I

2. A screen 'as described, comprising a solid metal frame composed of aunitary mass of metal rabbeted at its sides and presenting projectingguide ribs with springs.

mounted laterally of such ribs, and rails of wood presenting plain backadapted to'be planed for fitting tosides of a window frame, said railshaving grooves in the inner sides thereof to receive said ribs.

3. A screen" as described, comprising a solid one-piece metal framerabbeted at its sides and presenting relatively wide and thin Itransversely central guide ribs with springs mounted at thesides of suchribs, and rails of wood presenting relativelyv thick plain backsa'daptedfto be planed for fitting two sides on window frame, said railshaving grooves in the inner sides thereof to'receive theribs.

In testimony whereof, I have signed my name to this specification. 1
